Esta tesis se inscribe en el marco de la crítica literaria latinoamericana. Analiza, identifica y caracteriza en la obra ensayística y narrativa de R. H. Moreno-Durán y de Fernando Cruz Kronfly, dos escritores representativos de las últimas décadas del siglo XX en Colombia, las estrategias narrativas y los procedimientos de escritura a través de los cuales se hace visible, se procesa y se constituye la noción de comunidad, entendida como una categoría que refiere a múltiples modos en que los sujetos se relacionan los unos con los otros y con los cuales se problematizan categorías históricas como identidad, nación, Estado y sujeto. La particularidad de la obra de estos escritores ha sido identificada a partir de tres modos de figuración de la comunidad: la comunidad del desencanto, la comunidad melancólica y la comunidad de lo íntimo. Con esto, la tesis propone contribuir al conocimiento de la literatura colombiana de fin de siglo XX y caracterizarla dentro del contexto literario latinoamericano.

Project Completion Report, OWRT Project No. A-051-ARIZ / Agreement No. 14-31-0001-5003 / Project Dates: July 1974 - June 1975 / Acknowledgement: The work upon which this report is based was supported by funds provided by the United States Department of the Interior, Office of Water Research and Technology, as authorized under the Water Resources Research Act of 1978. / Bio-physicochemical measurements were made on treated sewage effluent releases at established locations within the channel of an ephemeral stream, the Santa Cruz River of Southern Arizona. Water samples were taken in chronological sequence as the effluent moved downstream, to trace changes in quality parameters during low and high hydrograph stages. Results indicate that dissolved oxygen (DO) concentrations at low effluent flows were higher than DO concentrations at high effluent flows; while, conversely, biochemical oxygen demand (BOD) concentrations at low effluent flows were generally lower than BOD concentrations at high effluent flows. Biochemical oxygen demand concentrations are affected by waste loadings, flow conditions, phytoplankton growth and nitrification. Mean river deoxygenation rates (k ) in sewage flows after six river miles from the Tucson Sewage Treatment Plant were always negative or increasing, indicative of nitrification, algal growth, and concentration of organic constituents through seepage losses.

Wastewater generated in the Tucson metropolitan region is conveyed to and treated at the Roger Road Wastewater Reclamation Facility (WRF) and Ina Road WRF. From 2005 to 2012, approximately 15,000 acre-feet per year of effluent was returned to the City of Tucson for additional filtration and reuse in the reclaimed water system. The remaining 48,000+ acre-feet per year of treated effluent was discharged to the Santa Cruz River, where a variable portion of the effluent infiltrates the streambed. The effluent that infiltrates the streambed contributes to recharge credits for participants invested in the Managed Underground Storage Facilities. In the effluent-dependent river, physical, chemical, and biological processes work in combination to develop a clogging layer near the streambed surface, which reduces infiltration. Previous studies have shown that large storm events have the ability to scour away the clogging layer and are the most significant processes contributing to establishing infiltration rates. Without the occurrence of large storm events, other variables such as effluent discharge and effluent concentrations affect infiltration to a lesser degree. Effluent discharge, biochemical oxygen demand, and total suspended solids are monitored and recorded daily at the outfalls of the WRFs. The parameters were investigated individually and in combination using statistical analyses to determine their correlations with streambed infiltration in the Santa Cruz River. The dry spring-early summer seasons from 2005 to 2012 were analyzed. A water balance was constructed for non-stormflow days during each time period. Evapotranspiration was calculated using riparian vegetation surveys and detailed delineations of aerial photography of the surface water and streamside herbaceous vegetation. Infiltration was derived as the residual of the water balance. At the daily time scale, correlations among variables were unobtainable due to the extremely variable characteristics of infiltration. The seasonal time scale analyses demonstrated an inverse relationship between both the effluent concentrations of biochemical oxygen demand and total suspended solids with infiltration and a direct correlation between effluent discharge and infiltration under extreme conditions. Under normal conditions, the distribution of discharge between Roger Road WRF and Ina Road WRF had a critical effect on infiltration as a result of the different deposition and erosive regimes through the Santa Cruz River.

This dissertation considers the intersection of aurality and visuality in seventeenth-century New Spanish poet Sor Juana Inés de la Cruz’s (1648/1651-95) acoustico-poetic discourse. Prior scholarship has focused either on the author’s engagement with Western music theory and compositional practices or else the role of musical references in her works. This has resulted in the marginalization of Sor Juana’s engagement with sound through disciplines that are not strictly musical or poetic, including: acoustics, cognitive theory and visual art. I address these lacunae by considering such concepts as echo, reflection, Ear, Voice, musica poetica (links between music and rhetoric) and musical pathos within the poet’s canon. Throughout my readings, Athanasius Kircher’s encyclopedic musical treatises— Musurgia universalis (1650) and Phonurgia nova (1673), both of which circulated within New Spain during Sor Juana’s lifetime—stand out as important sources by which such ideas were transmitted. My approach sharpens extant scholarship on these topics and identifies two new influences within Sor Juana’s poetic world: Aristotelian theories of cognition and Kircher’s unique position on musica poetica. More generally, this dissertation engages emerging scholarship on Ear in the early modern world and thus responds to the critical limits of ocularcentrism.

En esta tesis se plantea como objetivo general el estudio de la tecnología lítica y, principalmente, de las modalidades de utilización de los artefactos implementadas por los grupos cazadores-recolectores que habitaron la cuenca de los zanjones Rojo y Blanco de la Meseta Central de Santa Cruz. Los objetivos propuestos fueron realizados a partir del análisis tecno-morfológico y funcional de base microscópica de los conjuntos artefactuales procedentes de los sitios Cueva Maripe y Alero El Puesto 1 (AEP1), de la localidad arqueológica Piedra Museo. Las ocupaciones identificadas en estos sitios abarcan distintos bloques temporales que van desde la transición Pleistoceno-Holoceno al Holoceno Tardío (ca. 13.000 años C14 AP hasta tiempos históricos). La metodología aplicada, a partir de diferentes medios ópticos y mediante una intensa labor experimental, ha permitido determinar la recurrencia y variabilidad en usos y diseños de artefactos líticos durante los bloques temporales analizados en los distintos sectores de la cuenca. También permitió determinar las diferentes actividades que formaron parte de las prácticas cotidianas y rituales de los grupos que habitaron en el pasado. Los instrumentos líticos, manufacturados sobre diferentes materias primas, fueron utilizados para procesar distintos materiales, en primer lugar hueso, cuero y madera, seguido por materias blandas animales y vegetales no leñosas, mediante diferentes opciones técnicas. Estas actividades se repartieron en forma heterogénea tanto a nivel intrasitio como intersitio. Por otro lado, las diferencias establecidas a partir del estudio de las alteraciones postdepositacionales identificadas en los distintos conjuntos observados, permitieron discutir y profundizar el conocimiento acerca de los distintos procesos que intervinieron durante la formación del registro arqueológico, siendo el resultado de historias tafonómicas complejas. De esta forma los datos obtenidos han puesto de manifiesto las actividades efectuadas por las sociedades cazadoras-recolectoras mediante instrumentos líticos y la relación observada entre las variables de diseño y uso, permitiendo generar nuevos aportes a la discusión sobre la funcionalidad de los sitios y discutir la utilidad de conceptos teóricos en el estudio de la tecnología lítica. Por último, esta investigación permitió constatar aspectos económicos y simbólicos de las prácticas tecnológicas y formular la importancia que tuvo el contexto de uso de los instrumentos líticos en la organización social de los grupos que habitaron desde épocas tempranas este sector de la Meseta Central de Santa Cruz.
